Real Madrid came from behind to defeat Bayern Munich 2 - 1 in the UEFA Champions League quarter-final.
Cristiano Ronaldo scored both goals for the Spanish side to take his tally to European competitions to 100, the most by any player in the competition and the first to reach that tally.
Bayern bossed the early exchanges despite missing Robert Lewandowski through injury and should have gone ahead as early as the 10 minute but Muller fluffed his lines.
Bayern opened the scoring through Arturo Vidal who headed a corner kick past Keylor Navas.
Just before the end of the first half, the German side were awarded a penalty but Vidal who stepped up to take the spot-kick sent his effort way over the bar
The second half a different story with Real Madrid looking revitalized.
At the beginning of the second half, Ronaldo scored the equalizer with a volley from a right wing cross by Dani Carvajal.
Bayern's task became heavier when Javi Martinez was sent off in the 67th minute and Real capitalized through Ronaldo who gave the Spanish side the lead.
Carlo Ancelotti's side will travel to Madrid for the second leg knowing that his side must win by more than two goals to qualify for a sixth consecutive semi-final.
Zinedine Zidane won the competition as assistant to Ancelotti in 2014 before his triumph at the Madrid helm last year.
